This document is the gatherering of all the informations I have been able to find about this file format.

1.Structure

The sol file format is composed of a header and a data block. The data block contains all the variables stored.

2.Header

It is 16 bytes long and contains the following informations :

unknown : 2 bytes
size of the file after this tag (total size - 6) : 4 bytes [cardinal]
file type (guessed) : 4 bytes always "TCSO" 54 43 53 4F
unknown : 6 bytes always 00 04 00 00 00 00

3.Data block

The data block contains the name of the Shared Object : 2 bytes for the length of the string([unsigned word]) + the string([String]).

An unknown block of 4 bytes of 00 : 00 00 00 00

Then all the variables.

3.1 Item structure

All the variables inside the file root or inside an Object are structured this way :

length of the name : 2 bytes [unsigned word]
name :[String]
type : byte
data : size depends on the data type.
trailing 00 if outside an Object or Array

3.2 Data types

3.2.1 Number

type value : 00

8 bytes [double]

3.2.2 Boolean

type value : 01

1 byte [00 or 01]

3.2.3 String

type value : 02

length of the string : 2 bytes [unsigned word]

string [String]

3.2.4 Object

type value : 03

All the child items.

Ending tag : 00 00 09

3.2.5 Null

type value : 05

Nothing

3.2.6 Undefined

type value : 06

Nothing

3.2.7 Pointer

Id of the pointed Object, Xml or Array counting from the begining of the file starting by 1. 2 bytes [unsigned word]

3.2.8 Array

type value : 08

Number of items : 4 bytes [longunsigned word]

All the child items. (Names are strings even if only numbers are used)

Ending tag : 00 00 09

3.2.9 Date

type value : 11

Time-Date : 8 bytes [double]

integer part of the double is the number of days from 30/12/1899
the decimal part is the 24h hours divided.

Time zone : 2 bytes (time_zone * -60) [signed word]

3.2.10 XML

type value : 15

The XML is stored as a String with a length wich could be > 655535.

length of the string : 4 bytes [unsigned longword]

string [String]
